Best-in-Class Performance Features:
The reinforced narrow silhouette frame and ash profiles make a statement of style with their low-profile design. As a result, it creates a beautiful and expanded glass area. Furthermore, under the surface, internal chambers increase structural integrity, rigidity, and energy efficiency.
In addition, composite meeting-rail reinforcement allows for secure mounting of hardware. The non-conductive material helps reduce the transfer of energy.
Moreover, end-of-throw cam shift locking delivers increased strength and protection to the recessed lock. It also included an “unlocked” indicator.
Equally important, the smooth and uniform true sloped sill quickly directs water runoff without the use of weep holes. As a result, it keeps the exterior of the window clean and attractive.
Also, our telescoping sill dam delivers a triple payoff. Not only does it provide protection from air and water infiltration but also increases structural stability along with enhanced beauty.
When extreme window and weather hit, our proprietary sill interlock stands strong. Traditional sloped sill designs can allow the sash to bow during powerful windows. But, with our interlocking sash-to-sill technology, the sash is channeled firmly into the window frame for a unified wall of strength.
Finally, our innovative screen bulb seal creates a snug fit that eliminates light and insect penetration between the screen and frame. It also aids in easy screen installation and removal.
On our sliding windows, the sashes glide horizontally for easy opening and closing. Both sashes lift out for convenient cleaning. The nylon-encased dual brass roller system for smooth gliding performance.
Maximize your energy savings by choosing a high-performance SolarZone insulated glass package to meet your specific climate challenges. The lower the U-Value, the less energy you’ll need to heat your home. The lower the Solar Heat Coefficient (SHGC), the more you’ll conserve on air-conditioning..
